So if I want to test my metering I should shoot a white wall? how about a textured garage door with sun light to my back?

any uniform surface is fine, I use either the sidewalk, block wall, or paved roadway. The metering, if this is all it sees, will attempt to make it the same intensity

I know I am about to drive people nuts here, but I just don't think my camera is metering correctly. Where do I find this number that shows metering? attached are 2 shots from this afternoon.

what I do is use the histogram function in the photo editor, and measure the value of the grey scale. this should be 110.

Your first shot shows as 87 and the second as 91. this is abnout 1/2 stop under exposed.

What lens and camera, I can't seem to read any exif data

Are you using spot metering? For some odd reason Pentax D has about 1/2 stop difference in spot mode. Again I thought this was corrected since...

Those look like the old D metering pattern. Thought that was all changed w/ the newer models.
Thanks for the effort. Most people rarely try this and just keep posting images w/ soooo many variables that's it's impossible to get an idea of what really is the problem.
Ohhh, just dawned on me your using the kit lens. It's notorious for doing this. Not sure of the cause though.... that's really the likely problem. Got any other lenses?............

Original:

Gamma corrected:

Kit vs 100 Macro
AS you can see the kit is about a 1/2 stop off....
Same target, program exposure, same iso ect.
Screen capture has no exif of course...
